Don't think twice - Steve and his team are simply superb. As a +6 prescription and my first pair of varifocal glasses (+1.75 add), I was a little nervous but the Tokai 1.76 lenses are just outstanding in every respect. They were spot on from the instant I put them on. I was so impressed with Steve's knowledge, I also had two pairs of single vision sunglasses, again with the Tokai 1.76 lenses, which allowed me to go for slightly larger sunglasses frames than I have done previously. The lens edge thickness on my metal frames was unbelievable, and the plastic frames are virtually indistinguishable from the normal designer version that you would buy in the shops. Having worn glasses for 48 years, this buying experience was simply the best to date and worth every penny. If you want to see photographic proof, get in touch with Steve & I will happily send him some pictures.
